	Model 1			Model 2			Model 3
		95% CI			95% CI			95% CI
OHS	OR	Lower	Upper	OR	Lower	Upper	OR	Lower	Upper
				1.0			1.0
Minor symptoms	1.7	1.4	2.1	1.6	1.3	1.9	1.6	1.3	2.0

C statistic for the model	0.78			0.83			0.83

Model 1: OHS
Model 2: model 1 plus GCS, pupil reactivity, major extra-cranial injury and age
Model 3: model 2 plus CT findings (petechial haemorrhages, obliteration of the third ventricle or basal cisterns, subarachnoid bleed, midline shift, non evacuated haematoma)
